The main kiln body and a horizontal cylindrical is an angle of 3 ° placed on the roller. The material in the high end into the kiln, to do rotary movement function in the kiln, the material from a height (kiln) and tumbled to the lowest (kiln), at the same time, in the kiln head, a high pressure blower (coal or natural gas and other fuels) injected into the kiln, and the sufficient combustion the heat generated by the material, physical and chemical changes occur, the expansion, after cooling for ceramic.

Production of fly ash ceramsite should adopt double cylinder rotary kiln, namely the preheating segment kiln body and drying section can be separately to control its speed, according to the state of raw materials to control the preheating time. Clay ceramsite in recent years due to the land resource constraints, in some areas has been banned production and use. But in some areas can use the river silt, waste mountain soil and other production. The process is: raw materials mixing - granulating - Screening - sintering stacking and transportation (bagging).

Performance characteristics:

1. Has the advantages of simple structure, has high furnace unit volume, long service life, high efficiency, stable operation, high heat efficiency, low heat consumption;

2. Automatic temperature control, over temperature alarm, two time enters the wind heat utilization, long service life of kiln lining;
